Dydrogesterone, sold under the brand name Duphaston among others,[1] is a progestin medication which is used for a variety of indications, including threatened or recurrent miscarriage during pregnancy, dysfunctional bleeding, infertility due to luteal insufficiency, dysmenorrhea, endometriosis, secondary amenorrhea, irregular cycles, premenstrual syndrome, and as a component of menopausal hormone therapy.[7] It is taken by mouth.[7]

Side effects of dydrogesterone include menstrual irregularities, headache, nausea, breast tenderness, and others.[11][12] Dydrogesterone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[7][13] The medication is an atypical progestogen and does not inhibit ovulation.[7][14] It has weak antimineralocorticoid activity and no other important hormonal activity.[7][13]

Dydrogesterone was developed in the 1950s and introduced for medical use in 1961.[15] It is available widely throughout Europe, including in the United Kingdom, and is also marketed in Australia and elsewhere in the world.[3][15] The medication was previously available in the United States,[15] but it has been discontinued in that country.[16]
